Issue 149 which this release fixes is a fairly bad issue. For more details on the issue and caveats to it, read the notes in the issue.

- Fix rollback issue with nxos-ssh.
- Minor parsing fixes.

- Adds NXOS-SSH Support

Introduce `transport` optional arg, in-line with other drivers: https://github.com/napalm-automation/napalm-nxos/pull/94 thanks The-Loeki
